4PWM driver PCA9685 16 Channel I2C Module board

The PCA9685 board is a 16-channel PWM driver with an integrated clock. 16 channels. Its control system relies on the I2C protocol. The main power source required for the board is between 3.3 volts and 5 volts. It can be controlled via a 3.3-volt microcontroller, with a logic level range from 3.3 volts to 5.5 volts. It contains a total of 16 channels — can be connected to multiple controllers or LED lights. Used for robotic arms or robotic hands or robots consisting of many servo motors that require precision in movement.
